[SV49250( ALL)03/95]
In general, maintenance, replacement, or service
of the emissions control devices or systems in
your new Ford Motor Company vehicle or
engine may be performed at your expense by
any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.
*
[SV49300( ALL)05/95]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[SV49400(BEF )05/95]
RWARNING
On vehicles without original equipment
floor covering or insulation, do not let
passengers ride in your truck in a manner
that allows contact between skin and the
metal floor.
*
[SV49450( ALL)05/95]
If other than Ford or Motorcraft or Ford
authorized remanufactured parts are used for
maintenance, replacement, or for the service of
components affecting emissions control, the
owner should be assured that such parts are
warranted by their manufacturer to be
equivalent to genuine Ford Motor Company
parts in performance and durability. Please
consult your warranty information booklet for
complete warranty information.
*
[SV49500(BEF )05/95]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.

[SV49600( ALL)01/95]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
*
[SV49700( ALL)01/95]
By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device
or prevent it from working. In some of the
United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.
*
[SV49900( ALL)01/95]
Do not drive your vehicle if it does not operate
properly. See your dealer if the engine runs on
for more than five seconds after you shut it off
or if it misfires, surges, stalls, or backfires.
%*
[SV50000( ALL)05/95]
Information about your vehicle's emission
control system is on the Vehicle Emission
Control Information decal located on or near the
engine. This decal identifies engine displacement
and gives some tune-up specifications.

Readiness for Inspection/Maintenance
Testing
*
[SV51457( ALL)05/95]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a not ready for I/M testing condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount

342of driving required to reach the ready condition
varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
[SV51458( ALL)05/95]
OBD II Drive Cycle
[SV51459( ALL)04/95]
